The past ten years has seen a urry of research activity into the behavioural control of autonomous mobile robots. Yet despite this effort, many researchers are of the opinion that behavioural robots are incapable of achieving tasks more complex than simple can collecting, box pushing, herding or moving in formation. If such robots are to gain industrial(More)
In this article, we discuss the new constraints that will apply to future, highly dynamic networks and investigate one of the major problems that is likely to affect their deployment: traffic/workload distribution. Starting with a very simple model, we demonstrate that a structure made of undifferentiated subunits will almost inevitably hit a scalability(More)
1.1 The Team Agent Approach This paper describes a novel approach to dynamic distributed parallel processing using a mobile agent-based infrastructure. Our goal is to extend the concept of the Parallel Virtual Machine architecture [8] by using a combination of collaborative and mobile software agents to enable automatic and dynamic configuration of(More)
In this paper, an algorithm that forms a dynamic and self-organizing network is demonstrated. The hypothesis of this work is that in order to achieve a resilient and adaptive peer-to-peer (P2P) network, each network node must proactively maintain a minimum number of edges. Specifically, low-level communication protocols are not sufficient by themselves to(More)

do we understand where the real threats are? The point is, how many system administrators and public-key infrastructure experts can companies afford to employ or even recruit? Considering that devices and network channels will soon number in the billions, we would be wise to doubt enough skilled labor will exist. More important, even current threats are(More)
Balancing the conflicting demands imposed by a dynamic world on an autonomous robot requires a significant degree of adaptability. This paper describes a multi-layer control system for two co-operating mobile robots, which uses fuzzy logic to adapt the relative importance of a set of reactive behaviours. The fuzzy system therefore acts as an arbiter, which(More)
